Next time I'm in my boxed-up references I'll try to copy some pics, spent a little of my career converting trees into tissue, and venting dusts.Yeah, Brian, What kind of wood is it?
Do you have an electron microscope?
Would be interesting to see oak, ash, beech, pine and other kind of wood.
Would explain further what you see in the image that leads you to that conclusion? I understand about end grain and fasteners and gluing, but I am not sure what it is at this scale that drives it.This would make a pretty clear example to newbies on why end grain isn't great for fasteners or glue.
